We're dividing 72139323 by 102 
Let's see how many times 102 fits into 72139323.

Going ahead to step 1:
The number 102 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 102

Advancing to step 2:
102 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 102

Step 3:
102 can be fit into 721 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 7 after subtracting 714 from 721.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 102

Step 4:
When dividing 73 by 102, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 102

Going ahead to step 5:
739 divided by 102 is 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 707.0
If we subtract 714 from 739, we get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 102

On to step 6:
If we divide 253 by 102, we get 2 and a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 7072.0
If we subtract 204 from 253, we get 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 102

On to step 7:
492 divided by 102 is 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 70724.0
Subtract 408 from 492 to get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 102

Let's proceed to step 8:
If we divide 843 by 102, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 707248.0
If we subtract 816 from 843, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
If we divide 270 by 102, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 707248.2
If we subtract 204 from 270, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
When dividing 660 by 102, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 707248.26
If we subtract 612 from 660, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 102 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 707248.264
If we take 408 away from 480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 102, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 707248.2647
Deduct 714 from 720 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 102 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 707248.2647
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 102 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 707248.264705
The remainder is 90 after subtracting 510 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
900 divided by 102 is 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 707248.2647058
Subtract 816 from 900 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 16:
If we divide 840 by 102, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 707248.26470588
Subtracting 816 from 840 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 707248.26470588 with a balance of 2.4e-08.
